Life-course-persistent antisocial behavior may be associated with differences in brain structure
People with a life-long history of antisocial behavior had decreased mean surface area of the brain and lower mean cortical thickness than those with no history of antisocial behavior. Much of the cortical thinning was in areas associated with emotional regulation, motivation, and goal-directed behavior.... Read More...

Children’s mental health affected by sleep duration
Shorter sleep duration can increase the risk of children developing depression, anxiety, and cognitive problems. Children who routinely suffered sleep disruptions or shorter sleep durations had reduced brain volume in the orbitofrontal cortex, prefrontal cortex, precuneus, supramarginal gyrus, and temporal cortex....

Squid brains approach that of dogs
The first MRI-based mapping of the squid brain yields 145 new connections and pathways, 60% of which are linked to the motor and visual systems. The new brain map brings researchers one step closer to understanding how the squid can instantly camouflage itself.... Read More...
A rat had basically no brain, but it could still see, hear, smell, and feel
Rat R222 was born with hydrocephalus. Neuroimaging revealed most of its brain had compressed and collapsed as it filled with fluid. However, despite its condition, the animal was still able to see, hear, smell, and feel like other animals. The study sheds new light on neuroplasticity, and the findings could have implications for the development of new machine learning technologies.... Read More...
What people who don’t like music might tell us about social interaction
Musical anhedonia, a neurological condition where people don't enjoy music, affects 5% of the population. Researchers are exploring if this same condition could also be what impairs social bonding for some people on the autism spectrum.... Read More...
Music helps researchers find link between prediction and pleasure
Exposing subjects to music composed in an unfamiliar scale, researchers test whether reward can be derived solely from newly formed predictions.... Read More...
